...which reinforces my point about how people actually doing this and people speculating about it tend to respond to issues like this.
I take it you assume students are not creative enough to get the exact same result with Chrome? Because it is perfectly possible to do it. Unless of course you take steps to prevent that in Chrome. One way or another you either put in the work or the users will end up doing whatever they please. After configuring the OS doing the same for the browser is a relatively small step.
i'm belaboring this point now, but people who actually do this stuff know that you can't just throw up a GPO to fiddle with chrome settings and expect everything to work. this culture of "power users" thinking they know the best course of action for every situation in IT (and it's always "that thing i Put In The Work to do when i was tailoring my own system") is really silly.
